Why is Darwin's theory of evolution better than Lamrack's?
Darwin's explanation for the fact of evolution was better than Lamarck's explanation and fit the fact of evolution. Natural selection solved much of the species problem, but acquired characteristics did not have the empirical support and explained nothing in the end.
What question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Why did Darwin think giraffes are a good example of natural selections?
Actually, it was Lamarck who earlier introduced the giraffe as an example for evolution - Lamarckian evolution, to be sure. Lamarck proposed that there was some mechanism by which the short-necked ancestors of giraffes could acquire a change such that their offspring would have necks better suited to their needs. Darwin applied natural selection to the same example mainly because it had already been discussed in such detail.
How Lamarck an Darwin would have explained the large eyes of an owl?
Lamarck would explain the large eyes of an owl through the idea of inheritance of acquired characteristics, suggesting that owls developed larger eyes over generations due to a need for enhanced vision in low-light conditions, and this trait was passed on to their offspring. In contrast, Darwin would attribute the large eyes to natural selection, proposing that owls with larger eyes had a better chance of survival and hunting success in dim environments, leading to the proliferation of this advantageous trait over time.
Who most influenced Darwin's idea that some offspring are better suited to survival than others?
Charles Darwin was significantly influenced by the work of Thomas Malthus, particularly Malthus's ideas on population growth and resource limitations. Malthus argued that populations tend to outgrow their resources, leading to competition and a struggle for existence. This concept helped Darwin formulate his theory of natural selection, where those offspring better adapted to their environment are more likely to survive and reproduce. Additionally, the work of naturalists like Jean-Baptiste Lamarck and George Cuvier also contributed to his understanding of variation and adaptation.

How was Darwin's theory of evolution different from lamarcks?
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.

Darwin and Lamarck had different ideas about why all giraffes now have long necks why?
Lamarck would have said that the ancestors of modern-day giraffes had short necks but stretched their necks as they tried to reach leaves in trees; so, their descendants were born with longer necks. Darwin would have said that in a population of ancestral giraffes, some had slightly longer necks than others; the long-necked giraffes were better able to feed on tree leaves and as a result produced more offspring. Over time, the proportion of longnecked giraffes in the population increased.
How is lamarkism better than Darwinism?
Lamarkism is not considered better than Darwinism as it has been largely discredited in the scientific community. Darwinism, or modern evolutionary theory, is supported by evidence from genetics, comparative anatomy, and the fossil record. It provides a more comprehensive and accurate explanation for the mechanism of evolution through natural selection.

How would Lamarck and Darwin have explained the a duck's webbed feet?
As a results of duck of geneticVariation in duck population. *some had webbed feet than others *as results of not having webbed feet to compete for their food *duck with unWebbed feet Died *duck with Webbed feet Survive this called Natural Selection *The characteristics of Webbed feet acquired and pass on to the subsequently generations *All duck had webbed feet
Who understands evolution better then Darwin?
Darwin didn't fully understand evolution he came up with the theory.
How would Lamarck have explained the large eyes of an owl?
Darwin would have said that a few owls were born with bigger eyes. The owls with the big eyes would survive better and have more offspring so the owls with small eyes were less common untill there were only big eyed owls. This is called natural selection.
What is known as the fittest is Darwin's explanation for diversity in nature?
'Evolution of the fittest by natural evolution' is attributed to Darwin and Wallace. An alternate phrasing might be 'Failure of the least-fit by ... ', which equally (or better) explains the results.
